This world is usually considered by eastern religions to be an illusion, maya: i.e. not real.
If DMT can allow access to realms beyond THIS apparent reality, which appears to the experiencer as being MORE REAL than this reality, then it could be said that they have broken the veil of maya into a greater and more expansive reality beyond ours.
Is our "reality", the only "reality"?... I would have thought one of the first things that the DMT state seems to inspire in people is that there are many different realities, each as valid as the others.
This means that what people are being shown is that these realities are independant constructs, which are not dependant on an "observer" to manifest or project them into existence...
my mac "dictionary" philosophical definition of "reality" is:
"existence that is absolute, self-sufficient, or objective, and not subject to human decisions or conventions."
Some people, like Benny Shannon, assert that "all this" is in the mind...

If so, I would say that the mind is very, very strange that it would create these entities who SAY THEY ARE REAL, and do and "say" extraordinary things to the person who is experiencing them.
The problem with this view that "all is in mind" is that the material one encounters is often SO alien and outside of anything the mind has EVER consciously known... so where is the mind getting it from? And if this is the inner mind, is that not a very valid reality? If so, how did the inner mind come up with this stuff?
Benny Shannon says the mind is like the great mysterious frontier... truly though, I don't think there is a true "out there"... it all seem to be, "in there".
("the truth is IN there!" just isn't as glamourous though as the x-files version)
Regardless, it seems to me that the content of DMT experiences are beyond the generative potential of the usual monkey mind. The data is often experienced as being much more real than that usual data the mind receives (from the earth reality)
I personally, can't make much sense of the data at the best of times, which tends to imply to me that the data is coming from "elsewhere"... also, it is often not just data that is being imparted but a living relationship with other forms of sentience.
Yet, The first thing that many forms of this sentience say is that, 'we are you', but this may not mean that as soon as the DMT effect is expired they fall back into the empty abyss of Disney digital potential within... sometimes, though you can see the pixelations... and I believe many of these beings are very simple projections.
It's easy to differentiate, because the "complex" one's will blow you out of the water...
And if you watch them leave you, carefully, you can often see a radiant light coming through the crack in the layers of curtain they go through; and they may imply or gently communicate to you, that have other business to attend to elsewhere.
